VEHICLE-JACK.

Specification of Letters Patent.

Patented Apr. 24, 1917.

Application filed April 21, 1915. Serial No. 22,904.

To all whom it may concern:

Be it known that I, PARLEE H. RUssnLL, a citizen of the United States, residing at Van Buren, in the county of Hancock and State of Ohio, have invented certain new and use ful Improvements in Vehicle-Jacks, of which the following is a specification.

This invention relates generally to means for lifting the front or rear portion of vehicle bottoms off the ground, as they are moved into operative connection therewith, and is more especially intended to be used as an automobile jack in which the several parts are cooperatively so arranged that the momentum of the auto as it engages the jack carriage causes the said device to engage and retain the aXle and adjacent body structure in an elevated position, to relieve the tires from strain and to provide for readily and conveniently repairing and replacing tires or making other desired repairs.

The principal object of my invention is to provide a device of this character which consists of but a few simple and durable parts that are designed to cooperate in an eflicient manner with view of positively and efiectw ally supporting the jack carriage mechanism.

Another object is to provide an improved track means to be used in conjunction with the jack carriage in order to compensate for the movement of the latter during the stopping of the auto and to obviate the necessity of employing means for abruptly stopping the machine at a desired point such as would obviously derogate from the efliciency and utility of the device.

Other servient objects will become apparent during the continuance of the follow ing specification.

The above and other objects which will become apparent are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and more specifically pointed out in the appended claims.

In the accompanying drawings wherein is shown the preferred form of my invention, like characters designate like parts throughout the several views, and in which;

Figure 1 is a side elevation of my invention showing parts thereof broken away.

Fig. 9. is a front elevation.

Fig. 3 is a detail view.

Fig. 4 is a Sectional view taken on line 4.& of Fig. 3.

Fig. 5 is a perspective view of one of the axle engaging blocks.

In reducing my invention to practice, longitudinal supporting members 10 and 11 are first arranged on the ground or floor as the case may be, and secured in spaced relation by any desirable means. The members 10 and 11 may be constructed of any desirable material yet in view of the fact that the conditions will necessarily vary in concurrence with the adoption of my invention, I do not limit myself to any specific material.

Channel irons 12 and 13 are arranged on the respective supporting members 10 and 11 in order to form suitable track structures for guiding the jack carriage and the mecha nism carried thereby during the acking operation. Transverse brace rods 14: span the members 10 and 11 and have their respective extremities rigidly secured to the lifting blocks 15 and 16 as shown at 17 and 18 respectively. The rod 14 is also secured to the supporting members 10 and 11 as at 19 and 20 in order to reinforce the latter and obviate the danger of spreading during the operation of the device.

The front and rear edges of the lifting blocks 15 and 16 are cut slanting as at 21 and 22 in order to facilitate the operation of the machine thereon, so that the adjacent body structure of the latter will be lifted at a desirable angle, sufficient to cause the engagement of the adjacent axle with the respective axle engaging blocks, presently described.

In constructing the jack carriage and different component parts, complemental chair members are employed which consist of spaced apart side portions 23 and 24 having a suitable stirrup 25 formed therein as clearly shown in Fig. 3 from which project upstanding ears 26. The side portions and the stirrup formed therein are preferably constructed of a single section of material, in order to decrease the cost of manufacture and at the same time provide a more durable device.

Axle members 2? and 28 are journaled through the respective side portions 23 and 24: adjacent the ends thereof as shown in Fig. 1 in order to revolubly support suitable supporting wheels 29 and 30, the latter be ing designed to operate in the channel irons 12 and 13 in order to guide the jack carriage during the jacking operation. With view of spacing the supporting wheels from the inner faces of the side members 23 and 24, bearings 31 are arranged on the axles 27 and 28.

In order to connect the respective chair members, a transverse block or body 32 is employed which is seated in the opposite stirrups 25 as shown, the upstanding extensions 26 carrying suitable means 33 for securing the same in a rigid position, and thus eliminating spreading or otherwise lateral displacement of the chair members. Means may also be employed for connecting the body 32 and the respective side portions of the stirrups 25 as indicated by the numeral 34 in Fig. 1, however, it is to be understood that this form of fastening means is merely shown for sake of illustration and that other forms may be substituted in place thereof if it is so desired.

Spaced apart axle engaging blocks 35 are arranged on the body 32, which carry depending portions 36 that are secured to the adjacent portion of the body 32 by such means as shown at 37, the entire block forming a substantially inverted L-shaped structure. A series of openings 37 are arranged in proximity to the axle engaging blocks whereby the latter may be easily and quickly moved to various adjusted. positions. Vith view of limiting the movement of the axle on the respective blocks 35, upstanding plates 38 are secured to the front face of the body 32, and have connection with the fastening means 37 as shown in Fig. 1. However, other fastening means 39 are employed which have connection with the plates 38 and the respective block members 35 in order to efficiently support the same in a rigid position.

The material used in the construction of the blocks 35 and the respective plates 38, may be varied inaccordance with the existing conditions, and it'is to be understood that I am not limited to any specific form.

In the operation of my invention, the respective jack carriage is moved into the position shown in Fig. 1 adjacent the forward extremities of the adjacent irons 12 and 13 respectively. If the front portion of the machine or vehicle is to be lifted for purpose of repair or otherwise, the said machine or vehicle is operated so that the front wheels will engage the front inclined faces 21 of the lifting blocks 15 and 16. During the travel of the front wheels of the vehicle or machine on these inclined faces, the adjacent body structure will be lifted at an angle, so that the front axle portion will engage the upper face of the axle engaging blocks 35, the forward movement of the axle on the blocks being limited through the medium of the plates 38. The, vehicle is then brought to a stop, which in usual instances requires a distance of from 2 to 3 feet, during which operation the jack carriage will travel on the respective track means. After the jacking carriage is moved out of proximity to the lifting blocks it will be understood that the front wheels of the machine or vehicle will be in an elevated position '1 most practical and preferred embodiment is the most efficient, yet realizing that certain conditions will necessarily vary in concurrence with the adoption of my invention, I desire to emphasize the fact that various minor changes in details of construction and proportion of parts may be resorted to when required without sacrificing any of the ad vantages of my invention as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a device of the character described, a track structure, guide means, lifting blocks arranged in proximity to said guide means, a jack carriage movably mounted on said guide means, said carriage including complemental chair structures, and means connecting said chair structures, substantially as described.
